Piperazine Sulfonamides as Potent, Selective, and Orally Available 11β-Hydroxysteroid Dehydrogenase Type 1 Inhibitors with Efficacy in the Rat Cortisone-Induced Hyperinsulinemia Model
摘要:
11 beta-hydroxysteroid dehydrogenase type 1 (11 beta-HSD1) is the enzyme that converts cortisone to cortisol. Evidence suggests that selective inhibition of 11 beta-HSD1 could treat diabetes and metabolic syndrome. Presented herein are the synthesis, structure-activity relationship, and in vivo evaluation of piperazine sulfonamides as 11 beta HSD1 inhibitors. Through modification of our initial lead 5a, we have identified potent and selective 11 beta-HSD1 inhibitors such as 13q and 13u with good pharmacokinetic properties.
